' 1 rns'rnmne DEVICE.

Specification of Letters Patent.

Application filed November 22, 1916. l Serial No. 132,744.;

To all whom it may concern:

Be it known that I, JAooB W. KAISER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Fastening Devices, of which the following is a full, clear, and exact description. I

- This invention relates to a locking and fastening device by which two parts having sliding relationship with each other may he slid one over the other until in certain registering position when the locking device becomes effective and holds them locked in their relative position. I

Among other uses to which the invention may be ut I may mention that of securing and locking a cap upon the neck of a bottle, or holding a sleeve or ferrule on the neck of a bottle.

. Generally speaking, the invention may be said to comprise the elements and combinations thereof, set forth inthe accompanying claims. Reference should be had to the accompanying drawings forming a part of this specification, in which Figure 1 shows partly in elevation and partly in section the neck of a bottle having a cap in connection with which this invention may be employed; Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a transverse section through the cap along the line 22 of Fig. 1; and Fig. 4 shows another construction in which the locking-device of this invention may .be used. v In many constructions it is desirable to place a cap or similar member upon the neck of a bottle and to lock the cap or cylindrical member so that it can not be removed without destroying the bottle. This is useful where it is desired to prevent the original contents of the bottle from being disturbed untilit is used, and necessitating the practical destruction of the bottle or container when the contents is removed.

For instance, liquids shipped in bottles, if provided with acap and-locking-device as shown in this application, could not be tampered with, and the only way in which the contents of the bottle could be removed would be breaking the neck of the bottle.

This would so damage the bottle that itcould not be a ain used, and consequently would efi'ectua 1y prevent refilling of the bottle. Of course, in addition a cap may be 7 bottle.

used which will effectually seal the bottle.

against the admission of air.

Referr ng to the drawings, 1 represents the neck of a bottle which is provided with a groove in the exterior surface thereof, as

indicated at 3. This groove extends around w the bottle. and is of sufiicient depth to receive the locking spring later to be described. The cap member 4: which fits over the head of the neck of the bottle may upon the inside have a washer 5 which fits be- I tween the cap and the top of the bottle thus effecting a seal so asto prevent the admission of air or dust into the interior ofthe bottle.

is provided with a groove 6, which is in proper position-to aline withthe groove 3 when the cap is in proper position upon the This groove is preferablyformed,

. The cap upon the interior surface thereof 7 p as indicated in Fig. 3, that isto say, the

groove is not a continuous groove but is in reality made up of four grooves.- Each groove varies in depth from the deepest part until the wall of the groove is tangent with the inner surface of the cap. Between V the two oppositely disposed grooves there are projections 8 which serve in a manner about to be described.

Within the groove 3 there are two spring elements 9. Each of these spring elements are the same and are so made that they tend to expand outwardly. or away from the neck of the bottle. In assembling the cap upon the bottle the resilient members 9 are placed in the groove 3 upon the neck of the bottle, H

and are held in until the lower portion of the cap begins to slide over the groove 3. The cap will then temporarilv hold the spring 9 within the groove 3. When, however. the groove 6 comes to a position opposite the groove-3, the endsof the spring will immediately move away from the ne k of the bottle and into the grooves 6 which are formed in 'thecap 4. The centralportion of the resilient members can' not move out of the groove 3 because it will be noted central portion of the resilient members 9.

The lugs 8, it will be seen, separate adjacent ends of the two springs. Therefore, if the cap 4 be turned, the'springs will simply move around as the cap is turned, but there will be no opportunity to work the springs past each other and thus perhaps make one or more of the springs-1n:- operative as a locking spring.

1 The cap when thus locked to the neck of the bottle is, practically speaking, unremov able without destroying "the neck of the-bottle, and. this forms an effective lock.

In Fig. 4: I have shown another 'appl1cation for the locking device. In some 111- stances it is desired to attach a fixture to the end of a bottle. I may mention as an example of such 'a fixture, a device which willpermit the contents "of a receptacle or bottle to be emptied, and which will prevent the refilling of the bottle, Thesed'evices are usually made separately from the bottle to which they are to be attached, and it is common practice to hold the dev ce upon the bottle by spinning or otherwise securing a metal band-upon the neck oi the bottle and upon the lower portionof the non-refillable device.

It is, however, a very simple matter for a good mechanic to remove such a ferrule and after refilling the bottle, again spin a ferrule to ,hel'dfthe non-refillable attachment to the bottle and to' make so neat a job of it that it would not be detectable, at least by the average person.

The lock disclosed in this application may be utilized to hold the non-refillable attachment to, a bottle {and efiectually prevent, any such tampering as has heretofore been described.

In this connection, the neck of the bottle 10, is provided with a groove 1 1,the groove 11 being an annu-largroove of the same general description as the groove 3. The nonrefillable device which is designated at 12, is as here shown, provided with 'ash'ould'er 18 which is adapted to be engaged by a ferrule 1'4. This ferrule is preferably of porcelain or similar material, or of heavy metal so that it may not be tampered with without damaging it;

In the lower portion of the. ferrule llis a groove 15. This groove is similar in allrespect's to the groove 6 which is shown in 'cro'ss-section'in Fig. 3. The springslb cooperate with the grooves '11 and 15 in the same manner as that described with respect to the grooves 3 and 6. Thus it will be seen 'th'atthe ferrule 14 and the part 12 held thereby, are locked relative to each other.

It will be apparent that othermeans than a ferrule may be used to hold the non-re- Qo'pies of thispatent may he obtained for fillabledevice to the neck of the bottle, as for instance, the. ferrule 1e and the non-refillable device may be formed as one piece.

Having thus described any invention, what I claim is 1. The combination of two telescoping members which slidably engage each other,

groove formed in each of said members upon the surfaces which engage, the groove in one of said members "havin'gdeep-end portions and a central portion which extends outwardly and is substantially tangent to the surface of the other member, and a spring having ends which are adapted to spring outwardly, and occupy the deep portions of the groove last mentioned, the center portion of the springoccupying a part of the other of said grooves and substantially opposite the tangential part of the said groove whereby the cylindrical members are locked against sliding movement.

2. The combination of two telescoping inen'ibers which slidably engage each other, a groove formed in one of said members which is of substantially uniform depth, a

groove formed in the other of said members which has deep end portions, and a central portion which is substantially tangent to the inner wall of the member in which it is bers having two grooves, each of the grooves being deeper at their end portionswhile at the middle the groove portion is tangential to the surface of the member in which it is formed, projecting members separating the deep portions of the separate grooves from each other, and springs, each of which springs has end portions that are adapted tooccupy the deep portions of one of the said grooves, the central portion of each spring occupying a part of the other of said groo'i' es and oppositely disposed with respect to the tangential part of the before mentioned grooves whereby the cylindrical members are locked against sliding movement.

In testimony whereof, I hereunto aflix my signature.

JACOB W. KAISER.
